Transcription attenuation.
Prokaryotic transcription attenuation mechanisms are described in which different metabolic signals and sensing events are used to regulate transcription termination at sites preceding structural genes. Suggestive eukaryotic examples also are mentioned.
متن کاملTranscription attenuation in bacteria: theme and variations.
Premature termination of transcription, or attenuation, is an efficient RNA-based regulatory strategy that is commonly used in bacterial organisms. Attenuators are generally located in the 50 untranslated regions of genes or operons and combine a Rho-independent terminator, controlling transcription, with an RNA element that senses specific environmental signals. A striking diversity of sensing...

متن کاملBacterial gene regulation: from transcription attenuation to riboswitches and ribozymes.
Since the discovery of transcription attenuation as a mechanism of bacterial gene regulation, a broad variety of attenuation mechanisms have been unveiled and analysed. In 2002, the first convincing experimental evidence for metabolite-mediated attenuation, termed riboswitch, was published. Subsequently, riboswitches have been found to be widespread among bacteria and are also used in some euka...
متن کاملAnalysis of transcription asymmetries along the tRNAE-COB operon: evidence for transcription attenuation and rapid RNA degradation between coding sequences.
Mitochondrial gene expression in yeast is believed to be regulated predominantly at the post-transcriptional level. However, the contribution of mitochondrial transcription and RNA-turnover rates to differential gene regulation is still largely unknown. Mitochondrial run-on transcription and hybrid selection assays showed that some of the multigenic transcription units of the mitochondrial geno...
